Description

Inspired by the Lazzeroni proprietary cartridges, Remington introduced the 7mm Remington Ultra magnum in 2000. The 7mm RUM is based on the .300 Remington Ultra Magnum (1999) which is in turn based on a grossly modified version of the unbelted 404 Jeffery’s case. The RUM was designed to produce ultra-high velocities to meet the growing demand for long range hunting rifles and cartridges.

From a 26” barrel, the 7mm RUM typically achieves 3450fps with 140 grain bullets, 3275fps with 160-162 grain bullets and 3175fps with 175-180 grain bullets. Velocities ‘should’ in theory be higher than the 7mmSTW which has the same case length but a much narrower body resulting in less case capacity. Nevertheless, the law of diminishing returns relative to overbore capacity dictates that the RUM only achieves around 30fps higher velocity than the STW when both are hand loaded to optimum potential.
Since its introduction, the 7mm RUM has achieved a mild following among long range hunting enthusiasts. That said, it is a chambering which hunters generally eventually move away from due to short barrel life. The high cost of ammunition coupled with excessive throat erosion/ limited barrel life has limited the popularity of the 7mm RUM to dedicated long range enthusiasts. The RUM can be a lot of fun but its idiosyncrasies can lead to a level of frustration which eventually outweighs any benefits.

Each box contains 25 once fired brass shell casings.
All Nosler headstamps. This is unprocessed brass sourced from commercial shooting ranges. The casings have been washed and polished, but not resized and may still contain the spent primer.
It is recommended that all brass be inspected prior to being reloaded and fired.
